Klier last shared a photo of Thorne via Twitter at the end of July, following up a few days later with a tweet reading, "But an actress! How different an actress is! Harry! Why didn't you tell me that the only thing worth loving is an actress?"

In recent days, his social media presence has take a darker turn, as he tweeted to tell followers not to text him, and wrote on Monday, Aug. 25, "Has it ever been said that a man who throws himself out the window to escape from a fire is guilty of suicide?"

Thorne has remained even more cryptic on Twitter and Instagram, sharing a photo of herself waving after she confirmed the split, captioning the shot "Buh-bye," and linking to the Jason Derulo independence anthem "Ridin' Solo."
